I was looking at the list of WRAM Show vendors the other day and clicked on the link to KONDOR MODEL PRODUCTS. I stumbled on a large F-18 thats 68in long and has 44 in wing. Runs on two 90mm fans. Its a kit and its only $109 for the bare airframe. If I see it at the WRAMS...I may jump on it just for the sake of having it...even if I dont put it together right away! http://www.kmp.ca/product_info.php?c...fd64358ead7a6d

This is the Haoye jet that's been around for some time. I had one that flew on twin 70mm fans. Kevin Cox built one with a single 90mm and it flew well. It includes a lot of missiles, tanks, etc, as well

Be advised, there is no ducting either intake or outlet, and it requires a lot of cutting, and fabrication. See this thread:

Here's my conversion with a single 4" Haoye (hobbycity) fan on 10S 5000 and 2000 watts. A lot of work with custom designed wood bulkheads to create retract mounts and ducting formers. Way too much work but in the end I got a big F-18 for cheap and lightweight, 8.5 lbs. Clocked at about 97mph on radar recently straight and level, 120mph in a dive. Having gear doors would help, but it's fast enough to have the energy for large loops and a decent vertical climb.

Also, note that I used a single fan, that's the only way to get retracts in unless you have rotating retracts, which at this size might be doable. I must have retracts, I sacrificed enough models to the bungee gods, no more of that silliness for me thankyou.

Also know that I modded the inlet shape with a new foam piece on the outside, the original is like the HET arf, rectangular.

You might be better off with the Banana Hobby 90mm F-18, but I'd buy the kit version with no electronics, move the landing gear mounts forward, use Tamjets mini air retracts (unless you like fiddling with mechanical retract servos and burning them up), and take out the damn dihedral in the wing. F-18's don't have dihedral, they have a bit of droop in the wing (anhedral)!

...I wish we had a field where ANY wheels would work, retracts or not --- sigh ---...

Have fitted Spring Air 602's on my Starmax 90mm F-18. With a bit of ply reinforcement around the gear mounts and using the coiled steel legs with bigger wheels, she works a treat on the rough, rutted, partially grassed paddock we call a flying field. They also work in my twin 90mm MiG-29 which weighs in at ~10lb.

Unfortunately a tree jumped out in front of the F-18 recently , so I'm building another with the same undercarriage setup.

It is NOT however a twin 90mm fan setup, but a twin 70mm setup as someone else mentioned above. two 90mm would not fit well in this plane and its rather obvious they are 70mm fans given the power requirements are a 4s battery(instead of a 3s...check the description).
Could you mod in two 90mm fans? Probably, but the weight in batteries to power such a setup would make this size jet basically unflyable since it would require at least a 5s setup with a generous amount of mah capacity. Ive got the Fly Fly F-4(and also the BH 90 F-18) thats the same basic size as this Parkpilot KMP one and mine are running only ONE 90mm fan on 8s 5000.

BTW...those are the DSR2 46 electric metal gear retracts.

Edit:
All this being said...Fly Fly does make a twin 90mm russian Mig 29So...yeah its possible i guess to carry that much battery weight on this size airframe.

The one you link to is NOT the same one as KMP is selling. If you look at the specs, it calls for TWO 6s batteries. The specs on the Haoye one are slightly different as well.
The thread starter specifically mentioned KMP and the only F-18 KMP sells is the parkpilot foam one. That one is definitely NOT twin 90's
